AgentDraft vs. Cronofy.

Cronofy positions itself as the unified calendar API that handles availability, real-time push, conferencing-link generation, embeddable pickers, and enterprise-grade controls across Google, Microsoft 365, Apple, and on-prem Exchange. It's the canonical "spend a quarter building this yourself, or pay Cronofy" surface for human scheduling apps.

AgentDraft starts from a different problem. The 2026 reality isn't one human or one agent racing for a slot. It's N agents — yours, your vendors', your assistant's, your prospect's — racing each other on the same calendar. Cronofy gives those agents an excellent way to read and write a calendar. It does not tell you which of two agents wins when both want 3pm on Tuesday. That's the gap AgentDraft fills.

Cronofy's race story is the underlying provider's race story. Two agents call Create Event for the same slot; both succeed on the provider side; the calendar ends up double-booked unless the application layer above Cronofy implements its own coordination. Cronofy recently shipped an MCP server for agentic workflows, which is a real step — but MCP is a transport, not a coordination model.

AgentDraft resolves the same race at the storage layer. Every booking carries an agent_priority. The check is a DynamoDB ConditionExpression on the bucket row, so the check is the write — there is no application-level "is this slot free" window. In the collision benchmark, the rank-1 agent won 100.0% of races at p99 112 ms across 500 concurrent attempts, with 0 double-commits. Wire Cronofy underneath if you want — AgentDraft becomes the arbiter on top.

Cronofy's API plans start at $819/mo and rise to $2,399/mo (Growth), with enterprise tiers above that. The pricing reflects a real cost structure — connected calendars, real-time sync, enterprise SLA — and it makes sense for the scheduling-product audience Cronofy targets.

AgentDraft is built for the agent-developer audience and prices accordingly: $10/mo Individual, $25/mo Team, with Enterprise sized to the deployment. If you're an agent builder evaluating "what do I pay before my third paying customer?" the answer is materially different.

• Cronofy. You're shipping a human-scheduling product — a recruiter tool, a sales-rep round-robin, a customer-support booker — and you need turnkey availability, push, picker, and conferencing across enterprise providers. Their docs and SLA are the reason.
• AgentDraft. More than one agent will write to the same calendar — which is the direction every serious agent stack is heading. The conflict engine, the priority model, and the audited collision benchmark are the reason. The switching cost is the moat: once your agents are wired to AgentDraft, the coordination guarantees travel with them.
• Both. A reasonable pattern. Let Cronofy be the unified provider layer (sync, conferencing links, enterprise SSO/SLA); let AgentDraft be the agent coordination layer above it. They don't overlap on writes if AgentDraft owns the commit decision.
